SPECIFICATION forming part of Letters Patent No. 246,223, dated August23, 1881.

(No model.)

To all Iwhom it may concern:

Be it known that I, WILLIAM G. SEMPLE, a citizen of the United States,residing at Oincinnati, Hamilton county, Ohio, have invented new anduseful Improvements in Oar-Heaters, of which the following is aspecitication.

My invention relates to heaters for railwaycars, its object being toprovide an efficient, practicable, and economical device for thispurpose, adapted more especially for streetrailway cars.

To this end my invention consists in the construction of the heatingapparatus, and in the arrangement of the same in relation to the car,all as hereinafter more fully and at large set forth.

My invention, as adapted to a street-railway car, is illustrated in theaccompanying drawings, in which- Figure l is a vertical longitudinalsection of the entire apparatus. Fig. 2 is a plan view of the same. Fig.3 is across-sectional elevation of the same as viewed from the front.Fig. 4 is a partial cross-section7 showing the air-admitting device ineleva-tion; and Fig. 5 is a detached plan view ot' the air-admittingdevice.

Similar letters of reference indicate similar parts in bothspecitication and drawings.

In the embodiment of my invention shown in the drawings the apparatus issuspended beneath the front platform, B, of the car, between the centraland side sills, from a perforated foot-plate, G, which forms astandingplace for the driver, and is laid upon the sills, part of theiooring being removed for that purpose.

The apparatus consists, substantially, of a double-walled air-chamber,A, containing a stove or tire-pot, C, and provided with apertures forthe admission of the air from without, and terminates at the rear in atlue, L, by which the air is conveyed to a register, M, in the floorofthe car and there discharged'.

The apparatus rests upon a horizontal plate, D, ot' rectangular form,which is the bottom of the air-chamber, and is also the support for thefire-pot. The side walls, F F', of the airchamber are of sheet-iron,secured between the bottom plate, D, and an upper plate, D', said plateshaving low flanges on their corresponding surfaces, which areinterposedbetween and keep the walls F F' in proper position. The wall is doubledfor the purpose, as will be readily understood, of obtaining asurrounding space tor air or other non-conductor of heat, to preventloss by radiation, and the double wall is continued into and forms theair-conducting ilue L, for the same purpose. The upper plate, D', iscast with anges projecting upwardly around its edges, making a trough,which is filled with plaster-of-paris or other non-conductingiilling,and is inclined upwardly from front to rear at such an angle as willfacilitate the passage ofthe hea-ted air from the air-chamber toward andinto the conducting-flue L.

The entire apparatus is suspended by bolts c', extending downward fromthe foot-plate G through the plates D' and D, within the side walls, FF', and by means of sleeves azinterposed between the upper plate, D',and the foot-plate G,and nuts at the lower ends of the suspending-boltsthe parts are securely fastened together and suspended from thefootplate.

'lhe stove or furnace part of the apparatus fis consists of anopen-ended tire-pot, C, of rectangular horizontal section, with roundedcorners, which rests in a suitably-formed recess or within a flangeofthe bottom plate, D, and surrounds an opening in the bottom plate,across which the tilting grate c is hung, the pivot of which extendsrearward, and is provided with a suitably-formed arm, engaginga hook orother suitable fastening, for holding it in position, yet allow it to betilted and the tire-pot discharged when necessary. The tirepot O ishigher at the rear than in front, thus giving its top plate, E, aninclination upward at the rear-a construct-ion which facilitates theheating and passage ot' air above it, and also the passage ot' the gasesot' combustion to the exitp at the rear within the fire-pot. The plate Eis provided with an aperture extended upward into a throat or channel bya ange, E', passing through the upper plate, D', and is further providedwith a removable doublewalled cover, g, fitting closely the mouth.Directly above this, in the foot-plate G, is a corresponding opening,also fitted with a removable cover. Through these openings coal is fedthrough the throat E' into the tire-pot.

The provision for admitting air into the chamber surrounding theiire-pot is as follows: The bottom plate,D, is provided with aline ofperforations, d, around the tire-pot and within the side walls. Inaddition to these the airchamber is provided laterally on each side,near the front, with an opening, d', through the side walls, elongatedvertically. These latter openings have each a double-anged mouth-piece,r, opening to the front and rear, as shown in Figs. 2, 4, and 5, withwhich an automatic swinging gate, s, is connected, so as to guide thecurrent ot' air from either direction into the openings, and thusutilize the movement oi the car in either direction for obtaining aforced current ot' air into the heating-chamber. rIhe smoke-pipep isextended from the fire-pot G rearward horizontally within the tine L ashort distance, and thence is carried without the same laterally to apoint below the corner of' the car, where it is connected with aVertical pipe, p', extending up through the body of the car anddischarging over the root'. This discharge can also be made at the rearend of the car by carrying an ordinary smoke-pipe under the seatot theear.

The pipe p' is surrounded by a suitable casing as a protection forsurrounding objects against the heat.

I protect the front ot' the heater and the airopenings from becomingobstructed by dirt by suspending a wire screen, t, "ertically in frontofthe same, beneath the car.

The perforations in the foot-plate G allow the heat to rise through andwarm the plate suiciently to make it a comfortable standingplace in coldweather.

It will be observed that the entire heating apparatus is suspended uponand held together bythe bolts a', and that it is therefore readily takenapart for repairs, or removed from the carwhen not in use, by removingthe nuts below.

Having described my invention, I claim and desire to secure by LettersPatentl. In a railway-car-lleating apparatus, in combination with theinelosed stove or heater proper, the air-chamber A, constructed asdescribed and shown, consisting ot' the bottom plate, D, top plate, D',and side walls, F F', held between the upper and lower plates, and thcsuspendingebolts a', extending through the air-chamber and sustainingthe bottom plate, which supports the fire-pot C, substantially asspeeiiied.

2. rIlhe combination ot' the plates D and D', side walls, F F',suspending-bolts a', and thimbles t2 with the inclosed heater and therear air-conducting i'lue, L, substantially as speci` iied.

3. rIlhe combination of the irc'pot C, top plate, E, having thefeeding-throat E', removable cover g, surrounding air-chamber A, sidewalls, F F', top and bottom plates, D D', and bolts a', extendingthrough the air-chamber and sustaining the bottom plate, D, whichsupports the tire-pot, substantially as described.

4. In combination with the tire-pot C,having the inclined top plate,E,casings F F' and D', and rear conductingue, L, the ingressopenings land d', arranged as shown, thelatteropenings being provided withfunnel-mouths, substantially as and 'l'or the purposes set forth.

5. In combination with a street-car provided with a heater' arrangedbeneath the for ward platform, the screen t, substantially as and forthe purpose specified.

In testimony whereof I have hereunto set my hand in the presence ot' twosubscribing witnesses.

WILLIAM (i. SEMPLE.
